Turn heavy PNGs into light WebP files. For images headed to a website, this is the conversion that pays off most.
How to use it
- Drop in your PNG files.
- WebP is pre-selected as the output, with a quality control.
- Check the savings and download.
Your files are never uploaded
Everything runs inside your browser. Because the image never reaches a server, we cannot store it or look at it. That difference matters when the file is company material or a personal photo.
Frequently asked questions
- Is transparency kept?
- Yes. WebP can carry transparency, so a PNG's see-through background survives the conversion.
- Where should I not use WebP?
- Older editors and some upload forms still refuse it. It fits best for images you publish on the web yourself.
- Is it free?
- Yes. No account, no payment, no usage limit.
- Are my files uploaded?
- No. Everything happens inside your browser. A page that is already open keeps working even if you go offline.
- How many images at once?
- There is no count limit. Speed depends on your own device, because your computer does the work rather than a server.
